Sir, my brother s age is 19. Last year he had Thyphoid fever and was very weak. After using the prescribed drugs from the doctor , he became normal again. But after that his head started shivering. At first, we thought it was just due to weakness and did not take it seriously. But as it continued for several days , we consulted a neural specialist. He performed some physical tests and told it was just due to the tension and stress during the exam preparations, while he was preparing for competitive exams. He prescribed some medicines, and asked him to do some meditation . Though, the shivering (of the head) was controlled for few days, the problem reappeared again now. I have observed that the shivering is more for him mostly during the exams and especially in the summer. I just wanted to know whether it is only because of his exam stress or any other reason? I would also like to know whom he should consult to overcome with this problem, as it is most embarrassing in his college. Or can he just overcome this through physical exercises and meditation ?
